4GB memory in Blackbook?

You should check out the note on the bottom of the page: :)
NOTE: A 4.0GB (2GB x 2 Pair) configuration was also tested by 'popular demand'. Although the Core 2 Duo Macs are limited to 3.0GB addressed, the 4GB Set (2GB x 2 Pair) does appear enable 128 Bit addressing. While there does seem to be a small performance benefit gained with the 4.0GB vs. 3.0GB config, we'd recommend sticking with 3.0GBs max (in Core 2 Duos) unless you absolutely are seeking every last trickle of performance boost possible.
 
Interesting that under OWC's results for Halo, 2560MB (i.e. 2GB+512MB) was better than 3GB or 4GB of installed RAM.
 
The Macbook supports up to 2GB of RAM. At least that is mentioned on the Apple Website. The Macbook Pro supports 4GB (Santa Rosa) and the iMac 3GB.

It is strange, isn't it? If you look closely at the metrics for the other tests, 4GB actually gives quite a bit of a performance boost. I think OWC is being a little conservative in their wording.

You can use a "benchmark" to "prove" almost anything you'd want by picking a benchmark that will show better results under a given set of conditions. I'm not saying that the OWC results are bogus, but to gain more complete and accurate real-world insight additional testing that makes use of a broader range benchmarking methods is really needed.
 
The C2D Blackbooks support up to 3.3GB of memory. Although buying a 2GB module for the second slot only to have an additional 300MB addressed over a 1GB module seems like a waste of money to me.

But I believe that test results showed how the two even sticks of 2gb each did better than 1 gig stick with 1 2 gig stick. Something about the balance was mentioned above.

I guess we will see more results like 3dmarks and such when the prices fall further.
 
BTW the recent Barefeats testing of the new MBPs included results for a MB with 4GB.
